摘要: 目的:对10 种率的等效性检验方法的Ⅰ 型误差和检验效能进行比较, 并据此选择较好的方法估计样本含量, 以便实际工作者应用。方法:采用Monte Carlo 模拟试验。结果:10 种方法中, 以Dunnett-Gent 方法为最佳, 并按该方法估计了样本含量。模拟试验表明, 率的等效性检验所需要的样本含量非常大, 当试验组和参考组各只有100 例时, 任何等效性检验方法的检验效能均较低。结论:按目前国家食品药品监督管理局规定的最低样本含量100对,相应的检验效能很低,建议用统计学方法进行估计。

关键词: 百分率, 等效性检验, 检验效能, 样本含量, Monte Carlo

Abstract: Using Monte Carlo simulation to compare different test approaches, the results showed that Dunnett-Gent method was the best one of them both in type I error controlling and test power, and the statistical powers are very lower for all of 10 equivalence test methods when test group and reference group has only 100 cases.When establishing equivalence, 100 cases for each group suggested by State Food and Drug Administration (SFDA)is insufficiency, the required sample size should be estimated by statistical procedure.

Key words: test of equivalence on proportions, power, sample size
